SELECTING SYSTEM.

Specification of Letters Patent. Patented Apr. 1 1917.

Application filed September 11, 1915; Serial NI r. 50,176,

1 State of New Jersey, have invented certain new and useful Improvements in Selecting Systems, of which the following is a full, clear, concise, and exact description.

This invention relates to selecting syslo tems, and finds a particularly ready application in printing telegraph systems, although obviously not limited exclusively to this field.

i The invention belongs particularly to that class of selecting systems wherein the signal current impulses cooperate sequentially with a plurality of electromagnetically actuated devices, such as relays, and the elements of a; selectingvapparatus, whereby various combinations of such impulses produce characteristic results; and one of its rincipal objects is to reduce the number o electromagnetically actuated devices heretoforerequired in systems of this character.

Another objectof the invention is to provide a simple and improved arrangement of the above type for performingthe desired selecting operations at the remote end of a transmission line of such length'or under 80 such "cireumstances, that it"is' desirable to dispense with a no-current interval between 1m ulses.

, o the above ends, the invention, in ac cordance; vvith its general characteristics,

contemplates a series of interdependently and sequentially acting electromagnetically actuated devices; whose operations are dependent upon the' corresponding signal currentimpulses; and which co'iiperate to sue- 40 cessively associate the eleme1 1ts of a select 'i'ng ,apparatusvwith means responsive only to impulses of certain characterlstics, wherebyftlie signal impulses may variably afiect the. selecting apparatus Q The above and I the ,objects ot this invenei s and w l be mo y-by lie e is le t i i mgs a Fi re 1 vsethforth in thetfollowing .enn etibii qfye e f rmof the inventicn; Fig. 2 show'sra modification thereof, at 1d Fig. 3 is a diagrammatic representation of one'combination of signal current impulses. v i a The signal current impulsesvfor effecting the operation of the selecting system may be imparted to the transmission line L by any desired form 0E apparatus .The type of apparatus disclosed in the drawings comprises a circuit controller and distributer. The controller is co mposed of a plurality 0i pole changers 1, 2, 3, i and i -Whoseoperations' may be regulated by any -of the well-known manuallyactuated devices wherein-the controlling keys are arranged inthe form of an vordinary typewriter keyboard orb: .suitable automatic apparatus controlle b 1 av perforated paper tape" orinthe likes- The -1, 3 and 5 are connected tovthe posit'iveterminal of a grounded source oi energy 7,

The left-h and fixeduconjtacts of the fpole changers are associated ,With na pair of sources of energy 9and 10 such away that those pole changers whose shifts-lilo contacts are moved from the right-hand", to the left-hand fixed contacts, cause an in crease in the voltage normally supplied'by.

this increased voltage is shown'in thesecond and third im pulses. The movable contacts of pole changer-s1 to fifinclusivdBiefconnected to segments 11, 12, 13, 14 andx;15frespectively of a suitable current distribute]: D

The brush carryingarm .'of} th'e System, electromagnets dpreferably pic, that disclosed in Patent No. 1,103,133. comprise a ,olari'zed relay 19 an a neutral issued July 14, 1914, and the elements (ii-65 "'relay 20rhe polarized-relay 19 responds characteristically tocurrent impulses of both polarities. and of any voltage, that is a positive ulse moves its armature in one dare'etionan a negative impulse moves its armature in theopposite directiom On the I other-hand, the neutral relay 2 0 pulls u its armature in'responsepnly to 1m ulses av- 1ng certain characteristics; in t e embod1- ment shown, those impulses of either polarity whose volta es areincreased.

In operation, upon'thereceipt the first impulse of any combination of signalimses, polarized relay 19 moves its armature. 28 from contact 30 to contact 31, and a cir- -.cuit is completed from grounded source 29, armature 28, contact 31, conductor 33, armature 35 and relay 21 to ground.

' locking "by isseareassessare broken: andlthe apparatus returns to normal conditiodready "to receive a new combina-,. tion of impulses. v v I The modification disclosed in Fig. 2 allows one of the electromagnetically actuated devices to be dispensed with, armature 28 of relay 19 being connected to a condenser 100 instead of a source of energy. The sequentially acting relays 101, 1,02, 103 and 104 of the modified arrangement are divided into two groups of two relays each, relays 101 and 103 forming one group and being energized upon thedischarge of condenser 100, while relays 102 and 104, forming the second group, are energized upon the charging of condenser 100. .One,ter1ninal of the windings of relays 101 and 103, therefore, is grounded, while the corresponding terminal oflhe windings of relays 102 and 104 is re-' Spectively connected to sources of energy 105 and 106. It is understood that the relays of each group are to be energized successively in the manner set forth in describing the system illustrated in Fig. 1. Relays 101 to 104 inclusive are each provided with a. armature 107, which completes holding circuits through one of the back contacts and armatures 108 and 109 of clearout relay 110. Armature 108 is grounded, while armature 109 is connected to a grounded source of energy 112. Relay 101 is provided with an armature 115 cotiperatin with a back contact connected to' a grounde source ofenergy 116 and a front contact connected to an armature 117 of relay 103. Armature 117 cooperates with a back contact connected to relay 102, and a front C011. '40 tact connected to relay 104. Conductor 32 is extended through armature 120 and its back contact to relay 101 or through armature120 and its front contact and armature 121 of relay 104 to rela 103. Armatures 130, 131, 132 and 133 o relays 101 to 104 inclusive coiiperate with arn'iature 68 of relay to effect the energization of mechanisms 61 to inclusive of the selecting apparatus. i

In accordance with thisarrangement, the

- first impulse causing armature 28.0f relay 1 19 to engage contact 31 effects the charging of condenser 100 by source 116. If this impulse is of a higher voltage, relay 20 is also source 69: to operate energized, causi zl g I mechanism 61. e second impulse, return ing armature 28 to contact 30, discharges condenser 100 through conductor 32, armal,,.tu17..l29." relay 1, to ground, which fects the energiz'ation of relay'101, and the actuation of armatures 115, 107 and 130. The actuation of armature'l15 extends conductor 33 through armature 115 and front contactthereof, armature 117 and back coning circuits for relays 21 t0-25 inclusive are l; grounded battery "1055, he actuation of;

increased voltage fefiects the operation of the corresponding selecting mechanism 61 to 65 inclusive. When the so] active action is completed, the energizatior. of clear-out relay by any desired means returns the entire apparatus to normal.
